The Unveiling of the markers dedicated to Chico River heroes will highlight the Cordillera Day celebrations on April 28.

Led by the Cordillera People's Alliance (CPA), steel plates will be installed bearing the faces of Macli-ing Dulag, Pedro Dungoc Jr. and Lumbaya Gayudan in Tinglayan, Kalinga.

"With this marker, we remember not only the Chico heroes but what they fought for, land, life and honor; and what they fought against, militarization, government imposition of a destructive project such as the foiled attempt at the Chico dam," Abie anongos of the CPA said.

The plates were designed by Architect Vlad Longid and solar artist Jordan Mang-osan.

Anongos said the project to set up markers has long been planned and took years to complete.

Dulag is a known elder from Bugnay in Tinglayan, allegedly slain by the army because of his opposition to the Chico River basin project.

Dungoc is a teacher and martyr and was with Dulag during the struggle to stop the Chico River project.

Lumbaya is known as father of the tribes and was in the forefront of the Chico struggle during the Marcos regime.

The unveiling of the markers is the first part of 33rd Cordillera Day celebrations after which, delegates will proceed to Balantoy in Calbalan after the unveiling and program, for another program in Sitio Bolo.
